1995 LHS Chrysler air conditioning

1995 LHS there is no electrical power at the low pressure switch. Does it have an automatic climate control system? (Do you set a certain temp and the car makes it that temp inside the car?)

Have you traced the wires running to the low pressure switch to check for breaks or bad spots? You can test the wires for continuity to be sure they're a closed path for the electricity to take.

Have you checked the fuse for the a/c system?
